Inserting Tool V-COIL notch M 8 x 1.25

The V-COIL notch thread insert simply screws onto the inserting tool. The V-COIL notch inserting tool is equipped with a spring-loaded blade that engages with the drive notch of the screwed-on thread insert, holding it securely. Since the notches are present at both ends of the thread insert, you do not need to pay attention to which end of the thread insert points forward in the installation direction.

The V-COIL notch inserting tools feature a depth stop nut, which is adjusted to the intended insertion depth by a lock nut on the tool.

The thread insert is screwed into the receiving thread using the V-COIL notch inserting tool. Since the inserting tool is equipped with a ¼" hex drive on the drive side, it can be operated with all common bit holders. This is possible by hand, with cordless screwdrivers, or on stationary machines. Once the desired insertion depth is reached, you simply unscrew the inserting tool. The spring-loaded blade of the V-COIL notch inserting tool automatically retracts from the notch of the thread insert, releasing it.

Advantages:

• With Hex Drive: Compatible with all common ¼" bit holders for maximum flexibility.
• For Manual Operation or Cordless Drill: Allows use in various working environments.
• No Manual Adjustment During Installation: The spring-loaded blade securely holds and correctly aligns the insert.
• Handy even in Hard-to-Reach Areas: Compact design for optimal accessibility.
• No Tang Breaking: After installation, there is no need to manually break a tang, which saves time and reduces the risk of damage.

• Thread Reinforcement: Ideal for materials with low shear strength, such as aluminum and magnesium alloys, in mechanical engineering, automotive, electrical, and medical technology, as well as aerospace.
• Thread Repair: Perfect for repairing damaged or worn threads to restore original strength.
• Scrap Recovery: Enables cost-effective repair and reuse of faulty components.

1. Drilling: Drill out the damaged thread to the appropriate size with an STI spiral drill bit. Please note that larger drill holes may be required for thread-forming taps.
2. Check: Verify that the tap and thread insert match in thread type and pitch.
3. Thread Cutting: Cut the receiving thread into the drilled hole using special V-COIL taps. The use of cutting oil is highly recommended to increase tool life and ensure a clean thread.
4. Prepare Inserting Tool: Screw the tangless V-COIL notch insert onto the inserting tool. Ensure that the drive blade engages cleanly with the drive notch of the insert. The insert can be taken up from both sides, which simplifies handling.
5. Set Depth: Adjust the depth stop nut on the tool to the desired insertion depth and then firmly secure it with the lock nut.
6. Install Thread Insert: Screw the thread insert into the receiving thread with slight pressure and in the direction of the thread until the depth stop nut reaches the intended insertion depth.
7. Remove Tool: Simply unscrew the inserting tool. The spring-loaded blade of the tool automatically retracts from the drive notch, releasing the thread insert. There is no need to manually break a tang, which speeds up the process and makes it safer.
8. Result: After completing these steps, thanks to the tight and exact tolerances, as well as the formation of the spring thread, a thread will have been created that is often better and stronger than the original thread.

1. What is a V-COIL notch thread insert?
A V-COIL notch thread insert is a special wire-form thread insert used for reinforcing or repairing threads. The "notch" refers to the special indentation at both ends of the insert, which allows for easy and secure engagement by the V-COIL notch inserting tool without the need to break a tang.

2. Do I need special drill bits and taps for V-COIL notch inserts?
Yes, for the installation of V-COIL thread inserts, special STI (Screw Thread Insert) spiral drill bits and V-COIL taps are required. These are precisely matched to the specific dimensions and tolerances of the thread inserts.

3. Can I use the tool with a cordless drill?
Yes, thanks to the ¼" hex drive, the V-COIL notch inserting tool is ideally suited for use with cordless drills. This increases efficiency and reduces effort.

4. How do I correctly set the insertion depth?
The insertion depth is set using the depth stop nut. This is positioned on the tool to the desired depth and then firmly secured with the lock nut. Ensure that the adjustment is made before installing the thread insert.

5. Is the installation of V-COIL notch thread inserts easier than with conventional thread inserts?
Yes, installation is significantly easier and faster thanks to the tangless design and the spring-loaded blade of the inserting tool. The manual breaking of a tang is eliminated, which simplifies the process and minimizes the risk of errors or damage.
